Factories price and sample from what you send them. When details are missing, they fill the gaps with assumptions, and each assumption is a chance for the sample or the price to come back wrong. A tech pack removes the guesswork by describing the garment completely.
The pages a tech pack needs
- Cover page: style name and number, season, size range, colorways, your target price and quantity.
- Technical flats: clean front and back line drawings, with callouts for seams, pockets, stitching and details. Add close-ups of anything unusual.
- Measurement chart: points of measure (chest, waist, length, sleeve and so on) for your sample size, with how each is measured and the tolerance allowed.
- Grading: how measurements change from size to size, so the factory can produce the full size run.
- Bill of materials: every material and trim, with fabric composition and weight, color references, zipper type, button size, thread, labels and packaging.
- Construction details: seam types, stitch types, hem finishes and any special techniques such as bonding or flatlock seams.
- Artwork and placement: print and embroidery files, sizes, colors and exact positions.
- Labels and packing: main label, care label, size label and hangtag positions, plus folding, polybag and carton instructions.
The details that most often go missing
- Fabric weight and composition. "Cotton jersey" can mean very different fabrics. Give the blend and the weight.
- Color standards. Use Pantone references or a physical swatch, not a screen color.
- Tolerances. Without them, no one can say whether a measurement is right or wrong.
- Care label content. Garments sold in the US need fiber content, country of origin and care instructions on the label.
- Packing instructions. Folding, polybags and carton marks affect cost and how goods arrive at your warehouse.
You can still start. A reference garment plus written changes is enough for a first quote. A sourcing partner can build the tech pack with you during development.
Keep it a living document
Update the tech pack after every sample round. Date each version and note what changed, so the factory always works from the latest comments. The approved version becomes the standard that bulk production and the final inspection are checked against.
How Dragon Charm helps
Tech pack development is the first of our five production stages. We build tech packs from a concept, a sketch or a reference garment, then cost them across our factories. Read more about full-package production, or send us what you have and we'll tell you what's missing.
